preformance:
definitely a deafened report, but still a decent bang. Good can for the 5.7 to shoot without ear protection. Best for a .22 round for optimum quietness.
if you're wanting to just hear the slam of your bolt, this is not the can for the 5.7 round. But it does unscrew and come in half, for very easy cleaning, good for 5.7 recreation shooting without ear protection.

*I'd rate it at a 1... maybe a 2

Gemtech S-FN57. Designed for the FiveseveN and used by me on the FsN. Works as advertised with everything I've thrown at it (which is everything commercially available or available on the secondary market - FN, EA, [Baca - now defunct])

Supersonic rounds are quieter with the can, muzzle blast is significantly reduced, and muzzle flash is essentially eliminated. Muzzle flip is also reduced and there are POI shifts.

Subsonic rounds are a must for quietest operation.
I never was thrilled with SB193 (inconsistent cycling of the action), and strongly prefer EA's FsN-tuned QuieTOR or my pet loads.

Hollywood quiet is achievable with primer-only pellet rounds. These will not cycle the action, but they sure are fun.

Even with primer-only hand-loads, the set-up is only truly silent if I keep my finger off of the trigger. (I don't, however, let the pursuit of perfection get in the way of "good enough.")

Other considerations:
Adjustable sights or a red dot sight are a must if you want POI to coincide with POA. The added height of the red dot is a boon for a clear sight picture.

SWR Spectre is a great can for the IOM,USG.We just completed a silencer test July3rd 2010 and the Spectre was tested that day on an IOM with factory SS195.Results of the test(data)will be posted free to all on nfatalk.org under the review section.

I have an SWR spectre and have used it on my SBR PS90. It is hearing safe in my opinion. I haven't shot subsonic ammo so most of what you hear is the ballistic crack of the bullet. It is definitely alot more pleasant to shoot than unsuppressed. I just sent my five seven barrel off to be threaded so I don't have any experience with that as of yet. I would say the spectre would fall somewhere around a 2 or 3 on your scale. I've shot it into the ground in my back yard and no one called the cops. It would be hard to distinguish it as a gunshot except for the ballistic crack. It sounds similar to a pneumatic nail gun.
